FAQs
Does this bracket come with screws?
No, the bracket does not include masonry anchors or timber screws. You will need to source hardware appropriate for your specific surface material and post size.
Can I use this for fence posts on grass?
No, this is a bolt-down bracket designed for concrete or patio slabs. It is not suitable for direct soil installation.
How do I prevent the wood from rotting in the bracket?
The U-shape design elevates the post above the base, allowing for airflow. Additionally, ensure the timber used is pressure-treated for outdoor use.
Will the grey finish rust over time?
The bracket features a hot-dip zinc coating specifically designed to resist rust and corrosion in outdoor environments.
Can this be used for deck railings?
Yes, this bracket is suitable for securing timber posts for decking, pergolas, and fence applications where a solid, surface-mounted connection is required.
Troubleshooting
The post feels loose within the bracket
Ensure that the timber dimensions match the U-bracket size and consider using shims if there is a slight gap before tightening the side bolts.
The bracket is wobbling on the concrete
Verify that your concrete surface is perfectly flat. If the surface is uneven, you may need a leveling grout or a shim under the base plate to ensure full surface contact before tightening the masonry anchors.
Pros and Cons

- High-quality hot-dip zinc coating for rust resistance

Cons
- Fixing hardware (anchors and screws) is not included

Setup, Compatibility & Care
To install, ensure your concrete surface is level and clean. Position the bracket, mark the base plate holes, and use a masonry drill bit to create holes for your expansion bolts. Once the base is anchored, insert your timber post into the U-cradle and drive timber screws or carriage bolts through the side arms. For maintenance, periodically inspect the bolts for tightness after extreme weather events and check the zinc coating for any signs of surface damage. If you notice scratches, applying a cold-galvanizing spray can help maintain the protective barrier against rust.
